Give an "item" after button is pressed

Question

Not sure why the code block works wrong. I apologize in advance.

I have this game where i would like to keep track of the dialogs that have been played in order to give the player a "item"/"key" or show a new dialog.
I managed to make dialogs appear and disappear by creating buttons.
I would like that once the X button is pressed, the button will emit the visual dialog (this is working atm), and write itself inside a list that is located on a Global singleton (in order to keep a track of the texts.

The global.gd has a var called Data shown below

var Data = {
"Texts" : []
}

The objective of this "item" would be to keep a track of which dialog has already been played in order to: show a new dialog, open a new room.

My code for the button trying to get the "item" to appear on the global list

  extends Button

var mouse_enter = false
var clickable = true


# Called when the node enters the scene tree for the first time.
func _ready():
    $".".connect("mouse_entered", self, "_mouse_entered")
    $".".connect("mouse_exited", self, "_mouse_exited")

func _process(delta):
    if !$".".get_overlapping_areas():
        clickable = true

func _mouse_entered():
    Input.set_custom_mouse_cursor(Global.mouse_click)
    mouse_enter = true

func _mouse_exited():
    Input.set_custom_mouse_cursor(Global.mouse_norm)
    mouse_enter = false


func _unhandled_input(_event):
    if Input.is_action_just_pressed("mouse_click") and mouse_enter == true and clickable == true:
        Global.Data["Texts"].append(self.name.capitalize())
        _mouse_exited()
        print(Global.Data["Texts"])
        get_parent().get_node("ItemList").add_icon_item(self.texture)
        Global.save_data()
        self.queue_free()

My code for the scene that has the button and emits the signal (simplified)

extends Node2D

Dialogs

func unpause():
get_tree().paused = false

func onFarmer0pressed():
if getnodeornull('DialgNode') == null:
get_tree().paused = false
var dialog = Dialogic.start('Farmer0')

dialog.pausemode = Node.PAUSEMODE_PROCESS

    dialog.connect('timeline_end', self, 'unpause')
    add_child(dialog)

getnode("Farmer0").queuefree()

func onFarmer1pressed():
if getnodeornull('DialgNode') == null:
gettree().paused = false
var dialog = Dialogic.start('Farmer1')
dialog.pausemode = Node.PAUSEMODEPROCESS
dialog.connect('timelineend', self, 'unpause')
addchild(dialog)

Found a solution to the issue.
The way to make it work was to add the variable inside the signal pressed.

func _on_Woman1_pressed():
var a = "Woman1"
if !"a" in Global.Data["Texts"]:
    Global.Data["Texts"].append(a.capitalize())
    print(Global.Data["Texts"])
    Global.save_data()

if !"Cane" in Global.Data["Collected Objects"]:
    if get_node_or_null('DialgNode') == null:
        get_tree().paused = false
        var dialog = Dialogic.start('Farmer1')
#       dialog.pause_mode = Node.PAUSE_MODE_PROCESS
        dialog.connect('timeline_end', self, 'unpause')
        add_child(dialog)
        get_node("Woman1").queue_free()
else: 
    $Woman1.queue_free()

after it it was needed to add the function to hide in case that the name was on the list already
